Kepler One of the largest contributors to the field of astronomy was Johannes Kepler. His work was of utmost importance to the astronomy community as well as to other major fields of science. Using data collected by Tycho Brahe, to whom Kepler was an assistant, Kepler was able to formulate the three major laws of planetary motion. These laws give astronomers, physicists, mathematician

Nebula 时间:2013-11-13
Nebula NEBULA A nebula is a combination of dust particles and gases in space that form a cloud. They are the gaseous and dusty material expelled by an old star just before death.

All About Comets INTRODUCTION The picture of a comet is a spectacular object, with a brilliant head and a long tail, streaming across the heavens. Observations of the comet of 1577 by Tycho Brahe demonstrated that comets were more distant than the moon. Some comets are spectacular objects, but definitely the greatest numbers are not very bright, and many do not develop tails

Dark Matter Two people have been credited for determining the need for dark matter. The first was astronomer Jan Oort, who back in 1932 measured the perpendicular motions of nearby stars relative to the disk of our galaxy. By studying the gravitational influence of the disk on these stars he was able to calculate the mass of the disk. The value he determined was twice as much as that

These changes in water depth are caused by the gravitational pull of the moon and the sun, along with the depth of the water, and barometric pressure. The most important force on the tides is the moon. The gravitational force of the earth attracts all the water in the oceans, but it is also attracted to the
